Measuring system A measuring system generally comprises: the MyPro transmitter an inductive conductivity measuring cell with an integrated temperature sensor Pt 100 and a fixed cable a fitting for weld-mounting or an assembly for installation in a pipeline or tank MyPro CLM 431 MyPro CLD 431 with CLS 50 Conductivity measuring cells CLS 50 Measuring cable (permanently attached to sensor) Examples of measuring system configurations CLA 140 with CLS 50 TI195Y01.CDR Conductivity measuring cell CLS 50 Chemical industry / process engineering CLS 50 Application range of inductive conductivity measuring cell CLS 50 1 10 100 1 10 100 2000 µs/cm ms/cm Conductivity (uncompensated measuring range) TI195Y02.CDR The MyPro CLM 431 / CLD 431 transmitter has an overall measuring range of 0... 2000 ms/cm which may be spread as required by the application at hand. General information Measurement The inductive transmitter MyPro CLM 431 / CLD 431 can be switched from conductivity to concentration measurement. In the concentration measurement mode, several fixed concentration curves stored in the instrument and a user-programmable concentration curve are available: NaOH 0... 15% HNO 3 0... 20% H 2 SO 4 0... 30% / 96... 99.7% H 3 PO 4 0... 12% HCl 0... 15% The reliability and accuracy of the measurement are top priorities, particularly because inductive measurement is frequently subject to exacting conditions. For this reason, this version of the MyPro with its unique Sensor Check System, which monitors for ageing, breakage, short-circuit and moisture penetration, plays a leading role in this product segment. Cyclical automatic demagnetisation and a cyclical adjustment routine help to deliver accurate measured values at all times. 2
HART Handterminal 1 Offline 2 Online 3 Transfer 4 Frequenzg erät 5 Extras I O General information (continued) Self-diagnosis The MyPro permanently monitors the operating condition of the measuring system. 27 possible causes of errors are distinguished. Error conditions are signalled via the field display and the HART or Profibus interface and, in the case of HART communication, also via an error current signal (22 ma). Temperature compensation The MyPro offers several temperature compensation options: Linear compensation 0... 10%/K with the reference temperature selectable by the user Compensation according to IEC 746-3 for NaCl Compensation with programmable α table containing up to 10 elements. The temperature can either be measured continuously or entered as a fixed value. Operation Menu-guided operation The functions of the MyPro CLM 431 / CLD 431 are arranged at two different levels and can be accessed using four keys: Operating level 1 Viewing of current settings (secondary parameters) Error diagnosis (diagnostic parameters) Current output settings (parameter settings) Calibration Operating level 2 All other settings are located at this level, e.g. selection of conductivity or concentration measurement. The keypad is located underneath a protective cover to prevent unintentional actuation and soiling. No unauthorised access Configuration and calibration data are protected against undesirable modification by means of two access codes. Display The high-contrast liquid crystal display locks in at 90 angles to guarantee optimal readability in different mounting positions.

The digital communication signal is superimposed on the 4... 20 ma signal without altering it. The simple, straightforward design of the user interface provides convenient access to the entire functionality of the instrument. Commuwin II with Commubox Commuwin II is a graphical, PC-based operating program for intelligent measuring instruments. DDE interfaces (DDE = dynamic data exchange, Windows communication standard) are used for communication between Commuwin II and measuring transmitters. One DDE server (driver) per communication channel is available. Depending on the application, either the serial interface built into the personal computer or a special interface (card to be plugged into the PC) is used. The Commubox serves as the required interface module between the HART interface and the serial PC interface.
